The dietary, physical activity and sedentary behaviours of Victorian regional secondary school students

The aim of this study was to investigate the dietary, physical activity and sedentary behaviours of adolescents from four secondary schools in Warrnambool, regional Victoria. In 2004, a random sample of students (n=712), stratified by school year level, was generated from school enrolment databases and 443 students completed a lifestyle questionnaire. Twenty per cent of students were physically active for 60 minutes or more per day; 28 per cent used electronic media in free time for a maximum of two hours per day. Only seven per cent of students met these two Australian physical activity recommendations. Fruit, vegetables and dairy products were consumed every day by 39 per cent, 40 per cent and 71 per cent of students respectively; three serves per day of each of these foods are recommended for Australian adolescents. Compared with boys, girls were less physically active (p<0.001), consumed more fruit (p=0.011) and vegetables (p<0.001), but fewer dairy products (p<0.024). Seventeen per cent of students were overweight or obese; these students were less physically active than normal weight peers (p<0.018). The dietary, physical and sedentary behaviours of regional Victorian secondary school students in this study were inadequate when compared with Australian recommendations. Dietary and physical activity habits are still evolving in adolescence and unhealthy habits can still be changed.

Associations among individual, social, and environmental barriers and children's walking or cycling to school

Purpose. To examine associations among individual, social, and environmental barriers and children's walking or cycling to school.

Design. Exploratory cross-sectional study.

Setting. All eight capital cities in Australia.

Subjects. Parents (N = 720) of school-aged children (4-13 years; 27% response rate 49% parents of boys,).

Measures. Multivariate-adjusted odds ratios (OR) and 95% confidence intervals (CI) for parental reporting of barriers to their children's walking or cycling to school, based on a computer-assisted telephone interview.

Results. Forty-one percent of children walked or cycled to school at least once per week. Multivariable analyses found inverse associations with individual ("child prefers to be driven" [OR = 0.4, 95% CI = 0.3-0.6], "no time in the mornings" [OR 0.5, 95% CI = 0.3-0.8]); social ("worry child will take risk" [OR = 0.6, 95% CI = 0.3-0.9], "no other children to walk with" [OR = 0.7, 95% CI = 0.4-0.99], "no adults to walk with" [OR = 0.6, 95% CI = 0.4-0.9]); and environmental barriers ("too far to walk" [OR = 0.1, 95% CI = 0.0- 0.1], "no direct route" [OR = 0.4, 95% CI = 0.2-0. 7]) and positive associations with "concern child may he injured in a road accident" (OR = 1.9, 95% CI = 1.1-3.1) and active commuting.

Conclusion. Working with parents, schools, and local authorities to improve pedestrian, skills and environments may help to overcome barriers.

Prevalence of genital human papillomavirus DNA in a sample of senior school-aged women in the Australian Capital Territory

Background: A strong association between persistent infection with oncogenic types of human papillomavirus (HPV) and cervical cancer is well established. Small numbers of international studies examining adolescent HPV infection and the risk factors associated are published, but there is currently no evidence on the prevalence and risk factors for HPV in an Australian, sexually active female adolescent population. Methods: To provide prevalence and risk factors for HPV in a female sexually active, senior high school population in the Australian Capital Territory (ACT), a convenience sample of 161, 16–19-year-old females attending a senior high school was evaluated. The sample formed part of a larger sample recruited for a study of sexually transmitted infections and blood-borne viruses in senior high school students. A clinical record was used to collect information about sexual and other risk behaviours, while self-collected vaginal swabs were tested for HPV DNA detection and genotyping using polymerase chain reaction. Results: The prevalence of HPV DNA in this sample overall was 11.2%, with multiple genotypes in 38%. No statistically significant associations were found between HPV DNA and the number of male partners, age of coitarche, time since first sexually active, condom use, smoking or alcohol intake. Conclusions: This is the first Australian study that has examined the prevalence and risk factors for genital HPV in this demographic group. The prevalence of HPV infection is slightly lower than reported in similar age groups overseas and is lower than other Australian studies in older women and those attending sexual health centres. Of HPV-positive young women, high-risk genotypes were found in over half, with more than one-third of HPV existing as multiple genotypes. Large community-based prevalence studies are needed to guide the development of recommendations for the vaccination of young women against HPV and to support other health promotion initiatives.

Beyond the power of one : redesigning the work of school principals

There is mounting international research evidence that the work of school principals is increasingly difficult, time consuming and more unattractive to prospective applicants. We suggest that the solution to this situation lies in redesigning the work that principals do. Using the New London Group’s (1996) definition of design as both process and product and as a hybrid of existing resources, we offer five cases of redesign: distributed pedagogical leadership, co-principalship, shared principalship, multi-campus principalship, and community-based principalship. We argue that these examples show that redesigns that focus on the school, rather than on the work of the principal, have more far-reaching effects, but are also much more vulnerable to context. We propose three emerging principles for redesign viz. developing a strong warrant for redesign, attending to infrastructure and building organic relations between school and community.

Parent-reported health status of overweight and obese Australian primary school children: a cross-sectional population survey

Introduction: Childhood overweight/obesity is associated with poor physical and psychosocial health in clinical samples. However, there is little information on the health status of overweight and obese children in the community, who now represent a large proportion of the child population. We examined parent-reported child health and well-being and parent concern about child weight by body mass index (BMI) category in a population sample of primary school children.

Design: A stratified two-stage random cluster sample of 24 primary schools representative of the state of Victoria, Australia.

Measures: BMI (weight/height2) transformed to normalised Z-scores using the 1990 UK Growth Reference; the Child Health Questionnaire (CHQ), a 13-scale 50-item parent-completed measure of health and well-being; parent self-reported height and weight; parent concern about child's weight.

Results: Data were available for 2863 children aged 5-13 y (50.5% male), of whom 17% were overweight and 5.7% obese. Using logistic regression analyses with 'normal weight' as the referent category, obese boys were at greater risk of poor health (ie <15th centile) on seven of the 12 CHQ scales: Physical Functioning (odds ratio (OR) 2.8), Bodily Pain (OR 1.8), General Health (OR 3.5), Mental Health (OR 2.8), Self Esteem (OR 1.8), Parent Impact¾Emotional (OR 1.7) and Parent Impact¾Time (OR 1.9). Obese girls were at greater risk of poor health on only two scales: General Health (OR 2.1) and Self Esteem (OR 1.8). Forty-two percent of parents with obese children and 81% with overweight children did not report concern about their child's weight. Parents were more likely to report concern if the child was obese (OR 21.3), overweight (OR 3.5) or underweight (OR 5.4) than normal weight (P<0.05). Concern was not related to child gender, parental BMI or parental education after controlling for child BMI. Perceived health and well-being of overweight/obese children varied little by weight category of the reporting parent (overweight vs non-overweight).

Conclusions: Parents were more likely to report poorer health and well-being for overweight and obese children (particularly obese boys). Parental concern about their child's weight was strongly associated with their child's actual BMI. Despite this, most parents of overweight and obese children did not report poor health or well-being, and a high proportion did not report concern. This has implications for the early identification of such children and the success of prevention and intervention efforts.

Television, computer use and body mass index in Australian primary school children

Objective: To investigate relationships between children's body mass index (BMI) and parent reports of children's television and video game/computer habits, controlling for other potential risk factors for paediatric obesity.

Methods: Child BMI was calculated from measured height and weight collected in 1997 as part of a large, representative, cross-sectional study of children in Victoria, Australia. Parents reported the amount of time children watched television and used video games/computers, children's eating and activity habits, parental BMI and sociodemographic details.

Results: A total of 2862 children aged 5−13 years participated. Child mean BMI z-score was significantly related to television (F = 10.2₃, P < 0.001) but not video game/computer time (F = 2.2₃, P = 0.09), but accounted for only 1 and 0.2% of total BMI variance, respectively. When parental BMI, parental education, number of siblings, food intake, organized exercise and general activity level were included, television ceased to be independently significantly related to child BMI. Using adjusted logistic regression, the odds of being overweight and obese generally increased with increasing television viewing. No relationship was found for video game/computer use.
Conclusions: A small proportion of variance in child BMI was related to television, but not video game/computer time. This was far outweighed by the influence of other variables. Causal pathways are likely to be complex and interrelated.

A primary numeracy : a mapping review and analysis of Australian research in numeracy learning at the primary school level : report

The outcome from this project produces a database of over 185 projects and 726 publications relating to numeracy research to systematically ‘mapped’ Australian research on primary school numeracy over the last decade. The database incorporates research summaries and findings that are easily accessible to teachers and teacher educators, and act as a valuable tool for determining further research directions. The project report examines the available research and organises the discussion of the research findings under a set of themes and sub-themes.

Some summarised examples from the report reveals that:

* Effective teachers of numeracy:
- have high expectations of their students;
- focus on children’s mathematical learning, rather than on providing pleasant classroom experiences;
- provide a challenging curriculum;
- use higher-order questioning;
- make connections both within mathematics and between mathematics in different contexts; and
- use highly interactive teaching involvement with students in class discussion.

* Effective professional development programmes:
- provide teachers with the time and appropriate resources to enable them to reflect on their teaching;
- provide continuing support and encouragement while teachers explore possibilities and trial new strategies in their classrooms;
- involve teachers in school-based and wider networks;
- are of sufficient duration to allow significant changes to habitual beliefs and practices; and
- create opportunities for the exploration of theory-practice relationships.

Traffic safety education and health promoting school : a metropolitan and rural pilot study

Traffic Safety Education (TSE) is an important part of a school's program; however, it competes with many other components of schooling such as literacy, numeracy and a number of health areas. Hence TSE provision in Victorian schools has been somewhat fragmented and haphazard in its delivery. This small pilot study involved two metropolitan and two rural schools which attempted to link TSE into mainstream school activities through the new Victorian Essential Learning Standards (VELS) utilising the internationally accepted Health Promoting Schools (HPS) framework.
The findings of the pilot study showed that though schools face many demands, understanding and ownership of TSE is possible when administrative support, professional development and adequate planning time are made available. The report outlines several key recommendations to improve the delivery of Traffic Safety Education in Victorian schools.

`Out on the borderlands`: Time, generation and personal agency in women`s lives

What tools can we use in attempting to understand the recurring patterns of some girls’ early school leaving and consequent exclusion from well-paid employment? From which disciplinary fields can we take them? Using Bourdieu’s concept of the ‘scholastic point of view’ - the inherent intellectual bias of a discipline, in his case sociology - as a springboard, we suggest that if one turns to different ‘fields’, approaches might be found which point towards differing perspectives. This article brings Bourdieu into dialogue with the work of feminist historians and their conceptual tools. Carolyn Steedman’s notion of the politics of envy and Sally Alexander’s appropriation from psychoanalysis of the idea of repetition offer generative ways of exploring the ‘unthought categories of thought which delimit the thinkable and predetermine the thought’ (Bourdieu and Wacquant, 1992: 40). In their focus on gender, they have much in common with feminist sociologists’ responses to Bourdieu’s work, suggesting that a gendered ‘perspective’ offers a way of avoiding the ‘singular viewpoint’ inherent in any one discipline.

The successful school: a genuine trend or a statistical artifice?

Schools are increasingly being expected to make improvements based on data about students' learning outcomes. Such an expectation implies that principals, teachers and key personnel within systems can read and act upon the data available. There is evidence, however, that many people have poor understanding of statistical information, and that many factors inside and outside the school have an effect on students' outcomes. This study considers one primary school's data from statewide testing programs. Trends across time are considered as a basis for making judgments about the school's performance in improving students' learning outcomes in literacy and numeracy.

Investigation of the factors responsible for the superior performance of male students in standardised testing at one primary school

The project set out to investigate one primary school where, for four years or more, boys have outperformed girls in standardized Year 3 and 5 Basic Skills Tests in literacy and numeracy, which contradicts general findings on male and female performance in standardized literacy and numeracy testing. The school placed a heavy emphasis on literacy programs, which appear to be making a difference to the boys. Over time, there has been a slight improvement in boys’ literacy performance but the greatest area of growth is generally boys’ numeracy, rather than boys’ literacy.

Further aims of the study were to isolate school-based factors, which are potentially responsible for this phenomenon, from community-based factors and to explore the possibility that, rather than boys being advantaged, girls were actually being disadvantaged by practices at the school. The approach adopted by the research team employed intensive case-study methods and ethnographic approaches, including interviews, document analysis, and structured and unstructured observation of a range of school activities.

This paper describes how the school has transformed itself, the effects that this has had upon the teaching and learning environment and the results that have been achieved in the key areas of numeracy and literacy.

"Where myth becomes history" : the politics of mythical time in Heiner Muller's Medea

Heiner Müller in the 1980s produced a sequence of plays featuring Euripides’ heroine Medea using his distinctive, poetic modality of “the theatre of images”. These ostensibly postmodern narratives take the form of disjointed, visual and textual representations that are also fragmentations of historical and mythical times and spaces. Müller’s Medea plays are thus suggestive of the intersection between the discourses of history and myth — and the blending of historical time with ahistorical, supposedly “timeless” mythical narratives. Further, the postmodern possibility of history’s textuality to liquidate it into a type of (modern) mythology seeks expression in the plays’ representation of a converse equation: the moment signaled in the text as that “where myth becomes history”. This paper examines the problematisation of the myth-history dichotomy in Müller’s Medea plays, outlining the ways in which the “timeless” myth of the classical, infanticidal figure of Medea is strategically deployed to politicise evolutionist teleology, Western colonialism and the technologies of war in twentieth century Europe.
